We had performed eight incision radial keratotomy employing the American technique on 247 eyes of 166 patients from July, 1986 to December, 1987. The clinical results including postoperative uncorrected visual acuity, refractive power, and keratometric power were followed up at 6 months on 92(37.2%) of 247 cases. The results were as follows; 1. The mean postoperative uncorrected visual acuity was 0.595 and 60.9% of all cases had 20/40 or better uncorrected visual acuity. 2. The mean reduction in postoperative refractive power was 3.26 diopters. 3. The mean reduction in postoperative keratometric power was 3.08 diopters. 4. Operative and postoperative complications were visual fluctuation(142 eyes), photophobia(52 eyes), microperforation(7 eyes), transient increase of IOP(5 eyes), changes of peripheral cornea(6 eyes), and one case of postoperative cataract with persistent hypotony and uveitis.

PURPOSE: This study was undertaken to evaluate the clinical results of pars plana vitrectomy on posterior segment complications in posterior uveitis. METHODS: We reviewed the records of 20 eyes of 19 uveitis patients who were followed up for 6 months or more after vitrectomy. RESULTS: The mean follow-up period was 20 months. Final visual acuity improved in 10 eyes (50%), was maintained in 6 (30%), and decreased in 4 (20%). The mean improvement of vision was 1.6 lines (p=0.019). Detached retina was reattached in 8 (80%) among the 10 eyes with primary surgery. Postoperative complications were cataract (7 eyes), macular degeneration (2 eyes), retinal detachment (2 eyes), and recurrence (1 eye). CONCLUSIONS: These results suggest that pars plana vitrectomy may be a safe and effective treatment for posterior segment complications in posterior uveitis, but that early and complete vitrectomy should be considered for a better visual prognosis.

The authors report the result of cryo-extraction of the lens in 50 eyes (44 cases) which were operated in B.N.D. Hospital from January 1978 to April 1980. The results are as follows: 1. The incidences of complication during operation were hyphema(8%), vitreous loss and rupture of the lens capsule(2%). Hyphema was the most common complication during operation. 2. The incidences of early postoperative complication were striate keratitis(26%), hyphema (2%), shallow anterior chamber(2%) and uveitis. 3. The incidences of late postoperative complication were vitreous prolapse into anterior chamber (6%), updrawn pupil(6%), macular edema(4%) and posterior synechia (2%), corneal degeneration with abnormal tissue growth into anterior chamber (2%), iris atrophy (2%) and vitreous opacity (2%). 4. The postoperative final visual acuity more than 0.5 were 37 eyes(74%) and less than 0.1 were 2 eyes(4%).

6.Causes of Unsuccessful Visual Outcome after Cataract Surgery.
Journal of the Korean Ophthalmological Society 1997;38(5):781-787
We evaluated preoperative characteristics, intraoperative problems, and postoperative complications among the patients who underwent phacoemulsification and posterior chamber intraocular lens implantation by one surgeon. Eyes with postoperative visual acuity was lower than preoperatively or less than 0.4 on Han`s visual acuity chart were designated Group A, 68 eyes (16.4%), and the remaining eyes were Group B, 46 eyes (83.6%). Preoperative characteristics in Group A were uveitis (16.2%), diabetic retinopathy (13.2%), glaucoma (11.8%), macular abnormality (11.8%), etc. Intraoperative complications, posterior capsule reptures with vitreous loss occurred in 21 eyes (5.1%). 8 eyes (11.8%) of the 21 eyes were Group A, 13 eyes (3.8%) were Group B, and the difference between both groups were statistically significant (p<0.01). Postoperatively, cystoid macular edema was occurred in 12 eyes (2.9%). 11 eyes (16.2%) of 12 eyes were Group A, 1 eye (0.3%) was Group B, and the difference between both groups were statistically significant (p<0.01) and 4 eyes were preceded by posterior capsule rupture. From the above results, we recognized the importance of avoiding posterior capsule rupture with vitreous loss. If it does occur, we recommend that meticulous anterior vitrectomy be performed. Following these guidlines should reduce the rate of unsuccessful cataract sugery.

We reviewed the hospital records of 104 consecutive eyes in 101 patients who underwent pars plana vitrectomy at Presbyterian Medical Center from January 1993 to December 1995 and studied the postoperative visual acuity and postoperative complications. Possible indications for pars plana vitrectomy were follows: complications of proliferative diabetic retinopathy (30.7%),complications of other types of proliferative retinopathy except proliferative diabetic retinopathy(25.0%),complications of anterior segment surgeries (14.4%), complex retinal detachments(8.7%), intraocular inflammations and uveitis (8.7%), macular diseases (6.7%), and complications of ocular trauma (5.8%), Regarding postoperative final visual acuity, 53 eyes(51.0%) were improved, 30eyes(28.8%) were stabilized, 21eyes(20.2%) were worsened. Intraoperative or postopertive cataract, retinal breaks or retinal detachment were most frequent complications. We expected that pars plana vitrectomy might be indicated in various ocular diseases containing proliferative diabetic retinopathy.

Choroideremia is a rare hereditary disease with characteristic fundus that causes night blindness and peripheral visual field loss. The authors encounter choroideremia accompanied by recurrent uveitis. This paper is designed to give a description of the condition, along with an investigation of the literature. Ophthalmological tests and treatments were performed. Characteristic fundus, night blindness, peripheral visual field loss, electroretinography and other manifestations led us to a diagnosis of choroideremia. The anterior uveitis was managed with medication.

This study was undertaken to evaluate the effectiveness of pars plana vitrectomy in pars planitis and posterior uveitis. We performed pars plana vitrectomies in consecutive series of 31 eyes with pars planitis and posterior uveitis that were complicated with vitreous opacities, epiretinal membrane formation, tractional retinal detachment and posterior subcapsular cataract. Postoperatively improvement of visual acuity, 2 lines or more in Snellen chart, was noted in 19 eyes(61.2%) with a mean follow-up of 21 months. The inflammatory cells were not visible in anterior chamber or anterior vitreous after 1 month thereafter. In three patients, however, the postoperative visual acuities were worSe due to preoperatively combined cystoid macular edema, macular pucker and tractional retinal detachment. We believe early pars plana vitrectomy before the formation of epiretinal membrane is an important factor in minimizing and postoperative complications.
